2010-06-02sh: mach-sdk7786: conditionally disable PIO support.Paul Mundt1-0/+1
SDK7786 only supports PIO via the PCI I/O space, so we disable PIO completely for the non-PCI case. Signed-off-by: Paul Mundt <[email protected]>
2010-06-02sh: support for platforms without PIO.Paul Mundt8-34/+54
This extends some of the existing special casing for HAS_IOPORT platforms and gets it to the point where platforms can begin to conditionally select it. The major changes here are that the PIO routines themselves go away completely, including all of the machvec port mapping wrappers. With this in place it's possible for any non-machvec abusing platform to disable PIO completely. At present this is left as an opt-in until the abusers are the odd ones out instead of the majority.

2010-06-02usb: r8a66597-hcd pio to mmio accessor conversion.Paul Mundt2-15/+15
r8a66597-hcd is erroneously using PIO routines on MMIO registers, which presently blows up for any platform that elects to either override or do away with PIO routines. This managed to work for the common cases since the PIO routines were simply wrapped to their MMIO counterparts. This switches over to using the MMIO routines directly, and enables us to kill off a lot of superfluous casting in the process.

1) Use msecs_to_jiffies() instead of calculating by hand. 2) Call cancel_delayed_work_sync() instead of cancel_delayed_work() followed by a separate flush_workqueue(). 3) Remove the "tsc->wq = 0;" Sparse complains about that because tsc->wq is a pointer, not an int.

2010-06-01FS-Cache: Remove unneeded null checksDan Carpenter1-20/+16
fscache_write_op() makes unnecessary checks of the page variable to see if it is NULL. It can't be NULL at those points as the kernel would already have crashed a little higher up where we examined page->index. Furthermore, unless radix_tree_gang_lookup_tag() can return 1 but no page, a NULL pointer crash should not be encountered there as we can only get there if r_t_g_l_t() returned 1.

2010-06-01perf buildid-list: Fix --with-hits event processingArnaldo Carvalho de Melo1-1/+3
When we use plain 'perf buildid-list' we use only what is in the buildid table in the perf.data header. And those have absolute pathnames because at 'perf record' time we used __perf_session__process_events and that doesn't sets up the path shortening code in map__new() that happens if symbol_conf.full_paths is false, the default. On the other hand, when we use 'perf buildid-list --with-hits' we process all the events using perf_session__process_events, adding entries to the global DSO list _after_ removing the current directory from the DSO name, for presentation purposes. Because of that we end up having two entries in the DSO list when recording events for binaries using relative pathnames. Fix it minimally by setting symbol_conf.full_paths to true when marking the DSOs with hits in 'perf buildid-list --with-hits', as used by 'perf archive' Right fix longer term is to shorten the path only at presentation time. Will be done for 2.6.36. Reported-by: Stephane Eranian <[email protected]> Tested-by: Stephane Eranian <[email protected]> Cc: David S.

2010-06-01ath5k: wake queues on resetBruno Randolf1-14/+3
We can wake all queues after a chip reset since everything should be set up and we are ready to transmit. If we don't do that we might end up starting up with stopped queues, not beeing able to transmit. (This started to happen after "ath5k: clean up queue manipulation" but since periodic calibration also stopped and started the queues this effect was hidden most of the time). This way we can also get rid of the superfluous ath5k_reset_wake() function. Signed-off-by: Bruno Randolf <[email protected]> Acked-by: Nick Kossifidis <[email protected]> Signed-off-by: John W.

Commit 315e995c63a15cb4d4efdbfd70fe2db191917f7a is causing OOM kills when stress-testing a CIFS filesystem. The VFS readpages operation takes a page reference. The older code just handed this reference off to the page cache, but the new code takes an extra one. The simplest fix is to put the new reference after add_to_page_cache_lru.

quoting tcp(7): On individual connections, the socket buffer size must be set prior to the listen(2) or connect(2) calls in order to have it take effect. This adds a wrapper to do so, and uses it appropriately. Improves performance in certain situations.
